I'm looking to add either an external display to my 27" iMac or a LCD TV. My problem is I don't plan on watching any TV on the 2nd display - it's purely for work (web, e-mail, server management, etc.) - I have a lot of open windows/apps simultaneously. Should I buy a 27" Apple display to sit next to my iMac or put a LCD TV on the wall above/next to the iMac? Downsides to using a TV vs. a regular Apple display? If I use a LCD TV, I have a 40" 1080P LCD in my family room I can use - and I would replace that with a new LED TV.
